It should be time dependent, but there is a global variable relationship that calculates the x-velocity component of the boundary. It is linked to other things in the model, such as the concentration of the species at that point.

I guess a combined question would be why do I see the x-boundary move in the y-direction if this should be a 1-D problem? I know that is a basic question, but I'm curious.

how did you apply the growth velocity on the boundary conditions of ALE?

Hello guys,

I've been trying to use the ALE mesh mode to model a moving boundary oxidation model and I think I'm using it incorrectly. As the oxide grows, the boundary of the geometry has to move, is there a way to do that with ALE or should I look at using a different model?

Thanks,

Bobby
